Claims (7)

PatentansprüchePatent claims 1. Verbesserungen in Gehäusen für Zahnstangen-Lenksysteme, die insbesondere unerwünschte Geräusche in dem Gehäuse beseitigen sollen, umfassend einen Gehäusekasten, der am Fahrzeugrahmen starr befestigt ist, wobei eine Zahnstange in einem Gleitsitz an einer Endbuchse angebracht ist und die Zahnstange mit einem gezahnten Abschnitt an einem an dem Lenksäulenende befestigten Ritzel in Eingriff ist, wobei die Fahrzeuggelenklast, die axiale und radiale Komponenten erzeugt, eine Abstandswirkung zwischen den Ritzel- und Zahnstangenzähnen sowie eine Rückstellwirkung der Zahnstange in ihre Normalstellung definiert; gekennzeichnet durch die Verbesserung, daß die Zahnstange einen longitudinalen Keilschlitz aufweist, in dem ein gezahntes, lösbares Teil mit freiem radialen Spiel angebracht ist, und die Zahnstange in zwei Führungshülsen in gleitendem Eingriff ist, wobei das lösbare Teil, das an elastischen Mitteln angebracht ist, am Boden des Zahnstangen-Keilschlitzes angeordnet ist.1. Improvements in housings for rack and pinion steering systems, particularly intended to eliminate undesirable noise in the housing, comprising a housing box rigidly secured to the vehicle frame, a rack mounted in a sliding fit on an end sleeve, the rack engaging a toothed portion on a pinion mounted on the steering column end, the vehicle articulation load generating axial and radial components defining a spacing effect between the pinion and rack teeth and a restoring effect of the rack to its normal position; characterized by the improvement that the rack has a longitudinal key slot in which a toothed, releasable member with free radial play is mounted, and the rack is in sliding engagement in two guide sleeves, the releasable member mounted on resilient means being located at the bottom of the rack key slot. 2. Verbesserungen nach Anspruch 1, dadurch gekennzeichnet, daß der Gehäusekasten zwei einteilig mit ihm ausgebildete Führungshülsen aufweist und eine erste Endhülse und eine zweite Mittelhülse am Ende bzw. am mittleren Teil des Gehäusekastens angeordnet sind.2. Improvements according to claim 1, characterized in that the housing box has two guide sleeves formed in one piece with it and a first end sleeve and a second middle sleeve are arranged at the end and at the middle part of the housing box, respectively. 3. Verbesserung nach Anspruch 2, dadurch gekennzeichnet, daß die Mittelhülse zwischen der Endhülse und dem Ritzel angeordnet ist.3. Improvement according to claim 2, characterized in that the center sleeve is arranged between the end sleeve and the pinion. 4. Verbesserungen nach Anspruch 1, dadurch gekennzeichnet, daß die elastischen Mittel, die das lösbare Teil ständig gegen das Ritzel pressen, eine Gegenwirkung gegen die radiale Last definieren, die durch die Gelenkbaueinheit der Fahrzeugräder erzeugt wird.4. Improvements according to claim 1, characterized in that the elastic means which press the detachable part constantly against the pinion define a counteraction against the radial load generated by the articulation assembly of the vehicle wheels. 5. Verbesserungen nach Anspruch 1, dadurch gekennzeichnet, daß das lösbare Teil ein prismenförmiges, rechtwinkliges Teil ist.5. Improvements according to claim 1, characterized in that the detachable part is a prism-shaped, rectangular part. ti »nti »n DE/EP 1 120329T1EN/EP 1 120329T1 6. Verbesserungen nach Anspruch 1, dadurch gekennzeichnet, daß die elastischen Mittel, die in auf die Längsrichtung ausgerichteten Sitzen am Boden des Keilschlitzes untergebracht sind, auf einer Fläche des Teils ruhen, die der gezahnten Fläche des Teils gegenüberliegt.6. Improvements according to claim 1, characterized in that the elastic means, housed in longitudinally aligned seats at the bottom of the wedge slot, rest on a surface of the part opposite the toothed surface of the part. 7. Verbesserungen nach Anspruch 1, dadurch gekennzeichnet, daß die elastischen Mittel durch plattenförmige Unterlegscheiben, Federscheiben, O-Ringe oder dergleichen definiert sind.7. Improvements according to claim 1, characterized in that the elastic means are defined by plate-shaped washers, spring washers, O-rings or the like.
